Can National V Emission Standard Vehicles Still Be Registered in Henan Province?

Currently, National V emission standard vehicles can still be registered in Henan. Here is some relevant information about China's automotive emission standards: 1. Introduction to Automotive Emission Standards: Automotive emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Current Status of China's Automotive Emission Standards: China has its own national conditions, and the background for implementing emission standards differs from that of Europe. The most directly involved issue is the urban-rural disparity, so China should have its own standards. The pollutant emission limits in China's motor vehicle pollutant emission standards are generally equivalent to the EU emission standards, hence the similar terminology is used domestically, but there are still certain technical differences between the two.

Can a new car drive on the highway directly?

A new car can drive on the highway, but it is advisable to avoid sudden acceleration, sudden deceleration, full load, and aggressive driving behaviors. Here are some related introductions about driving on the highway: 1. Introduction to the highway: The highway refers to high-speed driving, which is compared to medium and low speeds. In an environment where low speed is the mainstream, low speed is considered normal or standard speed, while in an environment where medium speed is the mainstream, medium speed is considered normal or standard speed. 2. Precautions for driving on the highway: When driving on the highway, it is important to maintain a safe distance from the vehicle in front. When the speed is above 100km/h, keep a distance of more than 100 meters. There are distance confirmation signs on the highway, which can be used to confirm the distance. Stay away from trucks; when driving at high speed, do not drive side by side with trucks or follow closely behind them. Try to overtake trucks. Stay in the middle lane; the leftmost lane on the highway is the overtaking lane, while large trucks generally stay in the rightmost lane.

5W30 or 5W40 for All-Season Engine Oil?

Different vehicles require different engine oils. American, Japanese, and Korean cars generally perform best with 5W-30 oil, while German cars typically use 5W-40. Both 5W30 and 5W40 are all-season oils with similar cold-start performance. However, 5W-40 has higher viscosity than 5W-30, providing better protection under high-temperature conditions. Here is additional information: 1. Winter oils: Winter oil grades include 0W, 5W, 10W, 15W, 20W, and 25W. The "W" stands for winter, and the lower the number before it, the lower the oil's viscosity at low temperatures, the better its cold-flow performance, and the lower the minimum applicable temperature. 2. Summer oils: Summer oil grades include 20, 30, 40, and 50. The higher the number, the higher the viscosity and the higher the maximum applicable temperature. 3. All-season oils: All-season oil grades include 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W-30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, and 20W-50. The lower the winter number (indicating a lower minimum temperature), and the higher the summer number, the wider the applicable temperature range.

What Does a Three-Year or 100,000-Kilometer Car Warranty Cover?

ORA is Great Wall Motors' Ora brand. Ora ORA is a new energy vehicle brand under Great Wall Motors, but its name originates from a person, commemorating the world-renowned mathematician Mr. Euler. "Ora" symbolizes Great Wall Motors' commitment to meticulous craftsmanship and building high-quality cars. Ora's vehicle lineup includes: Ora Ballet Cat, Ora Black Cat, Ora iQ, Ora Punk Cat, Ora Good Cat, Ora Good Cat GT, Ora Lightning Cat, and Ora White Cat. Ora is Great Wall Motors' electric vehicle brand, established in 2018. Among Chinese automakers, Great Wall was the first to manage its new energy vehicle business as an independent brand. With the launch of the Ora ORA brand, China's first dedicated electric vehicle platform—the ME platform—was introduced. This platform integrates advanced smart and connected technologies from the chassis to the interior and exterior, achieving substantial breakthroughs in space, safety, and efficiency. The development milestones of Great Wall Ora are as follows: April 25, 2018: Debuted as Great Wall Motors' independent new energy brand at the Beijing International Auto Show. August 20, 2018: The Ora brand was officially launched. August 31, 2018: Ora iQ was released at the Chengdu Motor Show. April 2019: Ora iQ Travel Edition was launched. August 27, 2019: Ora R1 Family Edition was released. September 5, 2019: Two new series and five models of Ora's latest products were unveiled at the Chengdu Motor Show. July 24, 2020: Ora R1 was renamed Ora Black Cat and launched at the Chengdu Motor Show. January 14, 2021: Ora Black Cat Pet Edition was released. March 20, 2021: Ora announced a new brand positioning as a car brand that "loves women more," establishing the correct industry values for female users. May 17, 2022: Ora announced that the 2022 Ora Good Cat Morandi Edition was open for pre-orders.

What Are the Causes of High Temperature in Cars?

Engine's air charging coefficient decreases, abnormal engine combustion, engine oil deterioration, fuel supply system prone to vapor lock, and ignition system malfunction. Additional details: 1. Decrease in engine's air charging coefficient: Higher temperatures lead to lower air density, reducing the actual air intake of the engine; overheating of the engine increases the temperature under the hood, further decreasing the engine's air charging capability. The reduced air charging coefficient results in decreased engine power, causing the car to lose driving force. 2. Abnormal engine combustion: High ambient temperatures raise the temperature of the air-fuel mixture entering the cylinders, increasing the overall operating cycle temperature of the engine. Coupled with the radiator's reduced cooling efficiency, the engine becomes overheated. The end-gas mixture in the combustion chamber absorbs more heat, accelerating pre-flame reactions and increasing the likelihood of engine knocking. 3. Fuel supply system prone to vapor lock: Higher temperatures increase the temperature under the hood, making vapor lock more likely. When the fuel system heats up, some gasoline evaporates into gas, accumulating in the fuel lines and fuel pump, increasing fuel flow resistance and disrupting the vacuum created by the fuel pump during the suction stroke. This leads to insufficient or interrupted fuel supply, causing vapor lock in the fuel system. 4. Ignition system malfunction: When driving in high-temperature environments, the ignition coil can overheat, weakening the high-voltage spark and causing high-speed misfires. In severe cases, the ignition coil may burn out, affecting the car's normal operation.

What is the problem of high-speed body shaking?

High-speed body shaking issues are as follows: 1. Uneven brake disc surface: The brake disc surface is uneven with a large radial runout, caused by uneven braking force or brake pad misalignment. 2. Excessive tire pressure: When the vehicle's tire pressure is too high, the shaking is particularly noticeable when driving at high speeds on uneven roads, making it easy for the driver to feel the body shaking and veering. 3. Severe tire wear: Severe tire wear with significant imbalance in dynamic balance. Due to uneven wear or large dynamic imbalance, the tire may jump during high-speed operation, causing the body to shake. 4. Engine issues: Generally caused by fuel quality or ignition problems. At high speeds and under high load, fuel quality and ignition determine the power output. If either is abnormal, it can lead to engine weakness and shaking.
